Christian Benteke hobbled off the pitch in the first half of Aston Villa's match against Norwich on Saturday with a hip flexor injury and looks certain to miss Tuesday's League Cup match against Tottenham.
But the big Belgian won't be the only absentee, as Villa have seven other players in various states of disrepair.
Lambert revealed up to eight players - including Ashley Westwood, Antonio Luna, Gary Gardner and Chris Herd - are carrying knocks going into the Spurs showdown.
In addition, Gabby Agbonlahor, Fabian Delph and Ciaran Clark played through the pain barrier in the victory at Carrow Road.
Benteke is obviously Villa's biggest loss, but Gabriel Agbonlahor and Fabian Delph have also started the season in excellent form and have been hugely important to the team's performances this year. Meanwhile, injuries to Antonio Luna and Ciaran Clark, coupled with the season-ending injury recently suffered by new signing Jores Okore means Villa's already shaky back line could be in dreadful shape.
This is good news for a Spurs side which will likely see most of its key starting players rested for the match. Given the quality of Tottenham's depth right now, Spurs' second string squad have a great chance to progress to the next round over a Villa team shorn of almost all of its best players.
